Description:
24X17 in.
Notes:
[Map covers only a portion of the sheet.] and NOTE.—The Geological Survey makes contoured maps—three-dimension topographic maps—which are designed eventually to cover the whole United States, also Alaska, Hawaii, and Puerto Rico. The individual maps are projected to represent quadrangle areas rather than political divisions, and each map is designated by the name of some prominent town or natural feature within that area. The scales most commonly used are 1:24,000 (1 inch=2,000 feet), 1:31,680 (1 inch = % mile), 1: 62,500 (1 inch= about 1 mile), and 1:125,000 (1 inch = about 2 miles). A general description of topographic maps and a list of the symbols used are printed on the reverse of each sheet. About half of the continental area of the country, excluding Alaska, has been mapped, every State being represented. Connecticut, Delaware, the District of Columbia, Hawaii, Maryland, Massachusetts, New Hampshire, New York, Ohio, Rhode Island, and West Virginia are completely mapped. Maps of the regular size are sold by the Geological Survey at 20c. each. Except as otherwise indicated, a discount of 20 percent is allowed on an order for maps, or for maps and geologic folios, that amounts to $10.00 at the retail price. In ordering, give the name and scale of each map and the State in which the area lies.
